Ten of the game's 50 Achievements are unlocked in the recently detailed Zombies mode, including "Fuel Efficient", which requires players to find a different form of transport.

It also introduces Achievements for multiplayer, a first for a Call of Duty game.

Announced earlier this year, Black Ops 2 is set during a 21st-century Cold War and will release on November 13 on Xbox 360, PS3 and PC. A Wii U version will follow.

The game's campaign will feature usable drones and horses, as well as a robot enemy forced to fight in a devastated Los Angeles.

TranZit will be the primary zombie mode for Black Ops 2, adding context to the fight against the undead.

The mode will feature an expansive open world, which up to four players can explore either on foot or using the bus shown in the trailer below. The bus allows faster travel between locations, but can become difficult to escape from if overrun by zombies.
